Jmeter - how to properly send request name and reason on assertion failure

I am new to jmeter (I am using version 3.3) and I created a test plan with the goal of sending an email on Assertion failure.
in this email I want to add some information about the name of the request and its reason
so I have added and if controller with this condition:
${JMeterThread.last_sample_ok}
a beanshell preprocess with this script:
and an SMTP Sampler with this body:
and a response assertion:
I want to get an email anytime it hits the condition of response code=500 and the info described above.
I got to receive the email on that condition but the body message is literally this:
${body}
this is the assertion result:
what am I doing wrong?
How to get what I need?
Thanks

Your prev variable is not defined in the Beanshell PreProcessor (it exists only for PostProcessor and Listener, I would suggest using ctx.getPreviousResult() instead where ctx stands for JMeterContextService instance.
You also need to enable your HTTP Request GET - posts as this will be this "previous result" you're interested in.
Be aware that starting from JMeter 3.1 it is recommended to use Groovy for any form of scripting so consider migrating to JSR223 PreProcessor and Groovy language on next available opportunity. You should be even able to re-use the same code as I don't see any Beanshell-specific features in it. See Apache Groovy - Why and How You Should Use It article for more information on Groovy scripting in JMeter.

The script is sending an email if the last sampler is ok, therefore the assertion is ok too, so the body variable won't hold any value.
Just adjust your if statement to !${JMeterThread.last_sample_ok}, and then move up your HTTP sampler HTTP Request - POST/articles above the if controller.
This will make your script send an email if the sampler failed and you will have the body variable holding the failure message.

How to set additional authentication properties in apache camel DSL or inside the camel Processor?

Here I am trying to convert Json data to CSV format and finally send this file to Ofbiz server api but the api endpoint require some authentication content when I send parameter in URL I got the output below.
{"_ERROR_MESSAGE_":"Error calling event: org.apache.ofbiz.webapp.event.EventHandlerException: Found URL parameter [configId] passed to secure (https) request-map with uri [uploadAndImportFileFromCSVFile] with an event that calls service [uploadAndImportFile]; this is not allowed for security reasons! The data should be encrypted by making it part of the request body (a form field) instead of the request URL. Moreover it would be kind if you could create a Jira sub-task of https://issues.apache.org/jira/browse/OFBIZ-2330 (check before if a sub-task for this error does not exist). If you are not sure how to create a Jira issue please have a look before at https://cwiki.apache.org/confluence/display/OFBIZ/OFBiz+Contributors+Best+Practices Thank you in advance for your help.","sessionId":"someId.jvm1","removePathAlias":false,"loggedIn":true,"USERNAME":"__","_LOGIN_PASSED_":"TRUE","webSiteId":"API"}
After that I used MultipartBuilder to send request below.
exchange.getIn().setHeader("bearer",token);
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
File file =new File("//home/r2/Desktop/ofBizFile/orderFile.csv");
builder.addPart("configId",new StringBody("CON_ID"));
builder.addPart("fileTypeEnumId",new StringBody("CSV_FILE"));
builder.addPart("_uploadedFile_contentType",new StringBody("text/csv"));
builder.addPart("uploadedFile",new FileBody(file));
exchange.getIn().setBody(builder.build());
I also tried something like this.
exchange.setProperty(Exchange.CHARSET_NAME, "ISO-8859-1");
exchange.getIn().setHeader(Exchange.HTTP_QUERY,"USERNAME=abc&PASSWORD=bc69");
exchange.getIn().setBody("configId=CON_ID&fileTypeEnumId=CSV_FILE");
Here is my camel route
//Route 1
from("couchdb:http://localhost:5984/order")
.process(new JsonToCsvProcessor())
//Storing file into local directory
.to("file:/home/r2/Desktop/ofBizFile?fileExist=append&fileName=order-${date:now:yyyyMMdd}.csv");
.to("direct:jsonToCsv");
//Route 2
from("direct:jsonToCsv")
.setHeader(Exchange.HTTP_QUERY,constant("USERNAME=__&PASSWORD=__"))
//For get token
.to("https4://SomeAddress.com/centerAPI/getAuthenticationToken")
//Get the token and set required parameter for route 3
.process(new ProcessorGetToken())
.to("direct:hold");
//Route 3
from("direct:hold")
.setHeader(Exchange.HTTP_QUERY,constant("USERNAME=__&PASSWORD=__"))
.to("https4://SomeAddress.com/centerAPI/uploadAndImportFileFromCSVFile?throwExceptionOnFailure=false")
//How I know the file is submited successfuly ?
.to("stream:out").end();
So the problem is how I can send data inside the body in Route2 ProcessorGetToken for next Route3 ?

I'll give a shot into the dark here. Reading your error message:
The data should be encrypted by making it part of the request body (a form field) instead of the request URL
Don't you have a documentation about this integration? I think you need more clarification about this process and what's need to encrypt your data before sending it.
Also, try to set the Exchange.HTTP_METHOD to POST into your route, like this:
exchange.setProperty(Exchange.CHARSET_NAME, "ISO-8859-1");
exchange.getIn().setHeader(Exchange.HTTP_METHOD, "POST");
exchange.getIn().setHeader(Exchange.HTTP_QUERY,"USERNAME=abc&PASSWORD=bc69");
exchange.getIn().setBody("configId=CON_ID&fileTypeEnumId=CSV_FILE");
Take a look into this unit test to see more examples sending data over HTTP. There's also many other tests there.

HttpURLConnection "enctype" POST [duplicate]

How can I set content type of HTTP Put as xxxx+xml?
I was referring to solution in this link Android, sending XML via HTTP POST (SOAP). Its fine when we set content type like this, i mean the xml is came along with the request:
httppost.setHeader("Content-Type","application/soap+xml;charset=UTF-8");
but when i change type soap to something custom, the xml disappear on the request (i saw on the wireshark), like this:
httppost.setHeader("Content-Type","application/vnd.oma-pcc+xml;charset=UTF-8");
then, i tried put the xml only, so the request is ok again:
httppost.setHeader("Content-Type","application/xml;charset=UTF-8");
I want to know what exactly the rules for the content-type than come together with the xml type so that the xml still there.
Thanks.

Assuming you're using HTTPClient of 4.1.3 or greater -
When constructing you're entity, you have the option to specify the content being used for the POST or PUT operation for certain entities.
There is a ContentType object which should be used to specify this.
Using the factory method .create() you can specify the mimetype with a charset - the ContentType will be used by the framework to properly emit the header in question.
Example API call:
ContentType.create("application/vnd.oma-pcc+xml", CharSet.forName("UTF-8"));
NOTE Editing for HttpClient 4.1.2
In the case of 4.1.2, when you create your entity for the post or put operation, set the content type on the entity not the execution (HttpPost or HttpPut) using setContentType(String). This is deprecated in 4.1.3 and beyond.

Setting a custom Content-Range Header using Restlet

I'm using restlet 2.0.11 to provide data for a Dojo-based web application via a REST-Web-Interface.
According to the documentation of dojo, pagination is realized using the "content-range" header of HTTP, thus dojo expects a header like:
Content-Range: items 0-19/100
(Source: http://dojotoolkit.org/reference-guide/1.7/dojox/data/JsonRestStore.html)
Which means that the REST-Api provides the first 20 of 100 total items.
Setting the Content-Range header manually like this
getResponse().getAttributes().get("org.restlet.http.headers").add(new Parameter("Content-Range", "FooBar")
Results in the following error:
WARNING: Addition of the standard header "Content-Range" is not allowed. Please use the equivalent property in the Restlet API.
According to restlet's documentation the property is "message.entity.range" (Source: http://wiki.restlet.org/docs_2.0/130-restlet.html)
The direct modification of this hash-map was also without success:
getResponse().getAttributes().put("message.entity.range", "FooBat");
Another way which seemed to be promising is using the "Representation"-object of restlet, since it has a setRange() method, but during request time, the object reference is null:
getResponse().getEntity()
So my question is: How to set a Content-Range header to a Restlet response?

You have to use the equivalent Java properties in the Representation class, so this is getResponse().getEntity().setRange(myRange).

is there any tool to simulate http requests in java

I am trying to simulate HTTP requests in Java with the URL class and the HttpURLConnection class, the GET requests are easy to simulate while some POST requests seem harder because most POST request need Cookie in the request header. Some cookies were set by the HTTP response in the Set-Cookie field and I can get them by the function provided by HttpURLConnection, but I found that other cookies may be set by JavaScript and I have no way to handle them, so I wonder is there any packaged tool to simulate HTTP requests in Java?

try Apache commons Httpclient:
http://hc.apache.org/httpclient-3.x/

Why do you need to generate HTTP requests? Do you want to perform some stress tests?
I'd advise using something like JMeter (you can find a brief tutorial here).
Hope this helps something, it's better to avoid reinventing the wheel (if you need something like this, but it wasn't clear for me from your question).

For the cookie set with Javascript, you could try to parse the HTTP response, extract the cookie information and set it for your next request
For example, lets say, the response has code which calls a setCookie() function (setCookie is user-defined javascript function),
...
//some javascript code
setCookie("username", "johndoe");
//some more javascript
...
then you would extract the line setCookie() and the parse it for the name and value
